This recommended practice covers the maintenance of industrial and commercial power systems. It covers the fundamentals of electrical equipment maintenance, how to develop successful maintenance strategies, and the common testing methods used as part of an electrical equipment maintenance program.
Either for hardware or software repairable system, reliability analysis is very important. However, failure data analysis for repairable system is not an easy task. The widely used AMSAA model (power law process) is a kind of NHPP, corresponding to minimal repair. According to the variety of the reliability of repairable systems, accounting for the influences of the modification and repair, the repair...
The increasingly large demand for data storage has spurred on the development of systems that rely on the aggregate performance of multiple hard drives. In many of these applications, reliability and availability are of utmost importance. It is therefore necessary to closely scrutinize a complex storage system's reliability characteristics. In this paper, we use Markov models to rigorously demonstrate...
Root-cause diagnostics of generator service failures has become a major problem in the industry, particularly during the last 20 years. Generator maintenance specialists from OEMs and independent generator repair companies are trained to be proficient in a specific assignment - repairing of generators. Typically these specialists do not have the technical background to perform diagnosis of the root...
This paper illustrates a procedure to incorporate maintenance outages in substation and switching station reliability evaluation. Markov models of the station components and their application in creating mathematical models of station maintenance failure modes are presented. The method is illustrated by application to a switching station. The single station analysis is extended by application to all...
